i enrolled in course relational databases. asked research advantage of file based approach versus relational databases. i find easier understand relational databases having difficulty understanding file based systems. file based systems same storing files on windows hierarchical system, meaning text files stored under folders , directories? plain csv files example of file based system? when refer file-based databases mean databases interact with/update directly (via sql abstraction offered jdbc driver) in essence read/write file directly. example sqlite no, csv comma separated values file allows data saved in table structured format. a "flat file" database allows user specify data attributes (columns, datatypes, etc) 1 table @ time, storing attributes independantly of application. dbase iii , paradox examples of kind of database in cp/m , ms-dos environments, , original filemaker mac o/s example. a relational database takes "flat file" approach

i have tried bunch of libraries make rest post call using httpconnection in java asynchronously. have tried many open source libraries , none of them seems serve purpose. there way in core java. without knowing requirements or expectations: here simple example without proper error handling shows how async http call can done using java 8 public static void main(string ... args) throws interruptedexception, executionexception, timeoutexception { future<object> futureresult = getobjectasync(); object value = futureresult.get(500, timeunit.milliseconds); } public static future<object> getobjectasync() { return completablefuture.supplyasync(() -> dohttpcall()); } static object dohttpcall() { try { httpurlconnection urlconnection = (httpurlconnection) new url("http://example.net/something").openconnection(); urlconnection.setrequestmethod("post"); try (outputstreamwriter out = ne

i have 2 screens linked via tabbarnavigator : screena : upon pressing button, trigger function this.props.navigation.navigate('screenb', {data: 'test'} whereupon {data: 'test'} params . screenb : navigation page works expected. however, unable access params object - though can see in navigation dispatch log in console. i've looked @ react-navigation api, on link navigation props no avail. suggestions on how can programmatically access params on screenb? edits: my current navigation setup is: stacknavigator other scene drawernavigator another scene tabbarnavigator scenea sceneb when on sceneb, output of console.log(this.props.navigation.state) {key: "sceneb", routename: "sceneb"} . in screenb component, should able access params passed using this.props.navigation.state.params . kinda long, huh? so in case can do: console.log(this.props.navigation.state.params.data , see test !

i new react-native , building small app. have run odd problem. if json length, greater 9 section header not work properly. doing show , hide. have floating button, when pressed hides , in it's place shows input box. when exceed length of 9 section header, not force rendering. manipulate data, feel cheat myself out of learning experience. hopefully, have explained myself clearly. my json data looks this: [{ "id": "0", "service": "haircut" }, { "id": "1", "service": "brian" }, { "id": "2", "service": "cut&shave" }, { "id": "3", "service": "beard trim" }, { "id": "4", "service": "senior citizen haircut" }, { "id": "5", "service": "crew cut" }, { "id": "6", "

i'm newbie machine learning , tensorflow, using example tutorial source code, model trained , printed accuracy, doesn't include source code export model , variables , import predict new image. so revised source code export model, , create new python script predict using test data set. here source code export training model: mnist = input_data.read_data_sets(flags.data_dir, one_hot=true) print("run here3") # create model x = tf.placeholder(tf.float32, [none, 784], name="x") w = tf.variable(tf.zeros([784, 10]), name="w") b = tf.variable(tf.zeros([10])) y = tf.matmul(x, w) + b saver = tf.train.saver() sess = tf.interactivesession() ... ignore source code cost function definition , train model #after model trained, save variables , y tf.add_to_collection('w', w) tf.add_to_collection('b', b) tf.add_to_collection('y', y) saver.save(sess, 'result') in new python script, try restore model , re-execute y functio

it logical run multiple processes when multiple tabs there in google chrome found multiple processes under single tab only. thought thread stuck restarted pc , opened google chrome , found same behavior. using windows 7. chrome has plugins, web apps, rendering engines , others separate processes browser itself. that done if 1 of processes fails, won't affect whole browser, or whole tab, because separate processes too. for example, firefox doesn't have that, instead detects script in page should causing problem , shows dialog if want stop it. in summary: chrome treats these different processes: the browser the browser (yes, again. chrome it's 2 processes) each tab each extension (at least 1 per extension) each web app each plugin each whatever, process, yay! and helps things can run in parallel , that stuff doesn't end crashing whole browser.

so i'm working on building calculator mimics ones use everyday. have shown logic within function. when had cout lines (deleted, not shown anymore) see if "y" being correctly stores, , 2 variables, finalnum1 & 2, working, when going back, trying add new cout lines, nothing prints. if there more issues, feel free point them out, code unfinished, main concern nothing printing, understand code still needs work. if can that'd appreciated! int calculator::calculate() { if (userinput[0] != 'q' || 'q') // checks user input "quit" or "quit" { int stringsize; std::cin >> userinput; // user input stringsize = userinput.length(); int y = 0; while (y < stringsize) { if (isdigit(userinput[y])) {} else { posi = y; } y++; } first = userinput.substr(0,posi);

i have 2 php pages, , b. page has form, passes $_post['mode'] variable value 'edit' page b. page b has form, submit button named '_go'. page b checks if $_post['_go'] parameter set , process form within same page b. the problem that, on page b, if input value on form , submit form first time, works , success message. however, after success message, without refreshing page, re-input value , re-submit form, nothing , re-inputted value not processed. i looked myself, , found $_post['_mode'] cause of problem. when submit form first time, $_post['_mode'] 'edit'. when re-submit form, $_post['_mode'] still set value empty. i frustrated here. page b gets $_post['mode'] value 'edit' page a page b stores $_post['mode'] variable $mode, , value of $mode 'edit' page b submits form, $_post['_mode'] set , value of $_post['_mode'] 'edit'. page b re-submits form, s

as per understanding when want share particular part of author , publish,we use binary less replication. can use case,where should use binary less replication. i want know best practices of binary less replication. binaryless replication or shared data store works on basis binaries not copied across datastores. metadata replicated or transferred between instances. setup can applied between authors , publishers. alternatively data store can shared between author instances in cold standby setup. has 3 major use cases: when dealing large dam assets (high res images or videos), replication involving binary copies on network costly. binaryless shared data store binaries not copied , save on internal network traffic. saves time , cost setup. when have lots of publishers, binary copy can bottleneck author network. reduces load of transfer , publishers can scaled without impacting network usage exponentially. tarmk cold standby has limit of 2gb binary sync transfer across p
